The 'Ring-porous' wood is characterized by:

  1. Vessels of uniform size distributed evenly throughout the growth ring
  2. The complete absence of vessels
  3. Presence of tracheids only
  4. Large vessels in spring wood and small vessels in autumn wood
Show answer and explanation

Correct answer: Large vessels in spring wood and small vessels in autumn wood

Ring-porous wood shows a distinct difference in vessel diameter between early wood and late wood. This results in clearly visible growth rings due to the concentration of large pores in the spring wood.
